It will be appreciated that because of the prior art smart meter devices such as FDT/DTM (Field Device Tool/Device Type Manager) and EDDL (electronic Device Description Language), tend to communicate via the HART and Profibus protocols (Profibus-DP/PA). Therefore, the smart meter devices in the method provided by this embodiment, that is, the smart meter devices connected to the System (AMS, Asset Management System) corresponding to the method provided by this embodiment, may be the smart meter devices based on FDT/DTM and EDDL that support HART and Profibus protocols. The specific model of the smart meter device can be set by a designer according to a practical scene and user requirements, and the embodiment does not limit the model as long as the model can support HART and/or Profibus protocols for communication.

The communication agent device forwards the data message from the physical hardware to the hardware drive, the hardware drive analyzes the data message, carries out split processing according to different message headers, and delivers the data message with different protocols to the corresponding drive device for processing. Specifically, for example, HAMS (HOLLiAS Asset Management System, and time-of-interest device Management System) may communicate with the smart meter device supporting the HART protocol and Profibus protocol through hollyys DCS, MTL4850/4851, P + F MUX2700/KFD2-HMM-16, tripod real pbstudio1.0, and HART modem, as long as the data message sent by the connected smart meter device can be acquired, which is not limited in this embodiment.
Step 102: and judging whether the data message is the HART message or not according to the packet header of the data message. If yes, go to step 103; if not, go to step 104.
It can be understood that, because the method provided in this embodiment only shows that data management is performed on the smart meter device supporting communication of the HART and/or Profibus protocols, in this step, the packet header of the data packet is split, and it is only necessary to determine whether the data packet is a HART packet or not, and which type of the HART packet and the Profibus packet the data packet is. Of course, the purpose of this embodiment may also be achieved by determining whether the data packet is a Profibus packet, as long as the type of the data packet can be determined by splitting the packet header of the data packet, and for a specific determination manner, the type can be set by a designer according to a practical scenario and a user requirement. The present embodiment does not set any limit to this.

As long as the information meaning corresponding to the data message of the HART message type can be analyzed, this embodiment does not set any limitation.

Therefore, in the step, the data message is processed by using the Profibus driving device, and the parameter information of the intelligent instrument equipment can be obtained from the data table according to the type of the intelligent instrument equipment; and translating the data message by using the parameter information to acquire the information meaning corresponding to the data message. That is, the data message is translated according to the parameter information of the intelligent instrument device matched in the data table to obtain the specific information meaning, so that some packaged and supplemented information is extracted, and the information can be displayed in a unified manner.

If the data model is preset, acquiring parameter information from a DDL file corresponding to the type of the intelligent instrument equipment, and extracting the parameter information to a data table; the data table comprises the mapping relation between the type of the intelligent instrument equipment and the parameter information.
Specifically, the data structure of the DDL file corresponding to the smart meter device supporting the Profibus protocol may be as follows:
it can be understood that according to the type of the smart meter device and a preset data model, the position parameter information (SLOT) and the INDEX parameter Information (INDEX) are obtained from two types of data structures of a read COMMAND (COMMAND read _ xxx) and a write COMMAND (COMMAND write _ xxx) in a corresponding DDL file in an associated manner, other parameter information is extracted from the DDL file, and the corresponding parameter information is extracted into a mapping table (data table) of a database (SQLServer). And in the analysis process, acquiring parameter information of the intelligent instrument equipment from the data table according to the actual type of the intelligent instrument equipment. And translating the received data message of the intelligent instrument equipment by using the parameter information obtained by the data table to obtain the information meaning corresponding to the data message.

It can be understood that the purpose of this embodiment is to determine whether there is an intelligent instrument device that needs to be alerted according to the information meaning corresponding to the acquired data packet of each intelligent instrument device, and alert the intelligent instrument device that needs to be alerted by generating and displaying the alert information, so that a user can view the alert information on a corresponding display device.
It should be noted that, in the present embodiment, the alarm is performed by displaying the alarm information, and the alarm is performed by other methods such as an indicator light or a buzzer, which may also achieve the purpose of the present embodiment, and the present embodiment does not limit this. Specifically, the alarm information in this embodiment may include at least one of an alarm time, an alarm level, an alarm content, smart meter device information, and an alarm quantity, and may also include other information, which is not limited in this embodiment.

And processing information corresponding to the maintenance plan can be recorded, so that a data base is provided for later management. That is, the user may view the corresponding maintenance plan content in the maintenance plan interface, which may include: time, level, number of devices, processing status, etc. After the user processes the corresponding maintenance plan, corresponding processing information may be generated according to the maintenance plan, and the processing information is recorded one by one.

Based on any embodiment, when the user adds the smart meter device standing book module in the AMS, corresponding standing book data can be automatically generated. For example, when the user adds, deletes, and replaces the smart meter device for the AMS physical topology operation, the smart meter device data corresponding to the ledger module may also change simultaneously. Meanwhile, an intelligent instrument device which is not in the AMS device type library is added in the physical network, and then the information of the intelligent instrument device is added in the inventory module.
